bsp: u-boot: remove duplicate trusted-firmware-a dependency for SoCs with open DDR init

Browse Source 
For SoCs with open DDR init in U-Boot, there's no need for anything but
the BL31 from TF-A (maybe OP-TEE as well but that's off-topic) in
U-Boot. This is already handled by the TFA_DEPENDS variable outside of
this git context, so there's no need to duplicate it here.

By keeping the rockchip-rkbin dependency in INIT_FIRMWARE_DEPENDS and
use the PREFERRED_PROVIDER mechanism for selecting rockchip-rkbin as
provider for trusted-firmware-a as passed to TFA_DEPENDS, we make
explicit the dependency on two different pieces of software, though
currently provided by the same recipe.

The point being that this should prepare us and at the very least break
the build if we forget, for when open BL31 TF-A (so coming from
trusted-firmware-a recipe and not rockchip-rkbin) is released and we can
have rockchip-rkbin provide only the DDR bin and upstream TF-A provide
BL31 TF-A and still have a proper dependency scheme.
